750 W ATX 3.1 power supply

The Rosewill VMG750 is a 750 W ATX 3.1 compatible power supply built for modern desktop builds. Its full modular design keeps cable routing clean in compact cases. The unit includes a native 12+4-pin 12V-2x6 connector for current-generation graphics cards. A 120 mm FDB fan provides quiet cooling under load.

Single-rail capacity and excursion headroom

A single +12 V rail delivers the full 750 W to the system. The platform is rated for up to 235 % power excursion and 300 % GPU power excursion to absorb transient spikes. Hold-up time is 16 ms minimum at full load. Continuous output above the rated wattage is not supported.

ATX 3.1 and PCIe 5.1 interface limits

The supply meets ATX 3.0 and 3.1 timing and connector requirements. One 12V-2x6 cable supplies up to 600 W directly to a compatible GPU. Three 6+2-pin PCIe connectors remain available for additional cards or adapters. Builds needing more than one native 12V-2x6 connection or power beyond 750 W will require a higher-capacity unit.

Questions about this item

Will the 140 mm depth and 20+4-pin main connector fit my older ATX case and motherboard?

The 140 mm chassis and standard 20+4-pin main connector match legacy ATX dimensions, so the unit installs in older cases and boards without adapters.

How do I confirm the 120 mm FDB fan and 80 PLUS Gold efficiency are operating correctly after installation?

Listen for the 120 mm FDB fan spinning at low RPM under idle loads and verify system stability; the Gold badge means the PSU meets 85 % typical efficiency at 50 % load.

Which cables come attached and which must I add for a GPU needing the 12V-2x6 connector and six SATA drives?

The box includes the native 12+4-pin 12V-2x6 cable, three 6+2-pin PCIe cables, two 4+4-pin EPS cables and eight SATA connectors — enough for the GPU and six drives without extra purchases.
